In chemistry, a chemical formula is a way of presenting information about the chemical proportions of titles that constitute a particular chemical emulsion or patch, using chemical element symbols, figures, and occasionally also other symbols, similar as hiatuses, dashes, classes, commas, and plus() and disadvantage( −) signs.
These are limited to a single typographic line of symbols, which may include subscripts and subtitles.
A chemical formula may indicate certain simple chemical structures, it isn't the same as a full chemical structural formula.

The subscript number indicates the total number of titles of an element present in a patch.

While witting a chemical formula, first we've to write the symbol of an element and also write the number at the bottom of the symbol.

For illustration,

$C_6H_{12}O_6$ is the chemical formula of the glucose patch. The glucose patch is made up of six carbon titles, twelve hydrogen titles, and 6 oxygen titles.

The number 6 of the carbon snippet is written after and at the bottom ( lower- right) of the symbol of carbon element (C). also, the number 12 is written lower-right of the symbol of hydrogen element (H), and the number 6 is written lower-right of the symbol of oxygen element( O).

thus, the subscript figures tell us how numerous of the element to their upper-left there are in the patch.
